Abstract: This paper utilizes the establishment of data trading platforms as a quasi-natural experiment, based on the panel data of 283 cities in China from 2011 to 2022, and employs a multi-period difference-in-differences method to examine the impact of data element market construction on intelligent manufacturing. The findings show that the construction of data element market has significantly promoted the development of intelligent manufacturing. The results of heterogeneity analysis reveal that the impact of the construction of data element market on intelligent manufacturing is more significant in cities with superior digital infrastructure, greater openness of public data and stronger intellectual property protection. The mechanism analysis indicates that the construction of data element market fosters intelligent manufacturing through driving industrial structure upgrading and enhancing digital technology innovation. Furthermore, the construction of data element market not only boosts intelligent manufacturing locally, but also generates positive spillover effects on neighboring regions. The above conclusions provide scientific references and theoretical insights for advancing the construction of data element market and promoting the development of intelligent manufacturing.
